What ꣨ means
It's a Vedic chant mark, not the number eight. In the Sāmaveda — ancient Sanskrit hymns meant to be sung — digit-shaped marks sit above syllables to cue the chant's tones (svara).
The notation is old: a Sāmavedic manuscript dated 1583 puts numbers above text lines as gesture and tone cues. As of 2026, Unicode records no use of this exact eight in Sāmagāna; it was encoded for completeness, not because a chant needed it. Its working siblings — digits plus a few letters — belong to the Kauthuma and Rāṇāyanīya schools; Jaiminīya wrote cues between the lines.
How do I type ꣨ exactly?
Go by code point: U+A8E8, not the digit ८. Type a8e8 then Alt+X in Word, Ctrl+Shift+U a8e8 on Linux, or use a character viewer elsewhere.
One trap: the documented keystroke 8= produces ꣢꣯, a different two-mark sequence — a code labelled 'eight' can hand you the wrong mark.
Why does ꣨ appear to float or disappear?
Fonts and combining rules control the result. Alone it may hover over a dotted circle or blank space; a font without it draws a box — display trouble, not a different character.
Archival and specialist — outside Vedic text work it reads as a stray mark or font glitch.
Don't swap it for ८: readers see a floating or broken mark, not a normal eight.

2Is ꣨ a numeral?
No. Use ८ for the ordinary Devanagari eight — ꣨ is a chant mark with no recorded Sāmagāna use.
Can ꣨ vanish on screen?
It can — weak glyph support or combining layout can hide or misplace it; display trouble, not a different character.
